News media coverage and the epidemiology of homicide

OBJECTIVES This study assessed how newspaper coverage of homicides corresponds to the epidemiology of homicide. METHODS Stories in the Los Angeles Times about homicide (n = 2782) were compared with the homicides that occurred in Los Angeles County from 1990 through 1994 (n = 9442). The generalized linear model assessed how victim, incident, and suspect characteristics related to coverage. RESULTS Even when multiple variables were taken into account, some homicides (those with female, child, or elderly victims; those in which the suspect was a stranger to the victim; those in wealthier neighborhoods) received more coverage and others (those with Black or Hispanic victims or victims with less than a high school education; those committed with nonfirearm weapons; those in which the suspect was an intimate of the victim) received less coverage than expected. CONCLUSIONS Some homicides are more newsworthy than others. Potential implications of not providing the public with representative data are discussed.

Developing a Practical Forecasting Screener for Domestic Violence Incidents

In this article, the authors report on the development of a short screening tool that deputies in the Los Angeles Sheriff’s Department could use in the field to help forecast domestic violence incidents in particular households. The data come from more than 500 households to which sheriff’s deputies were dispatched in fall 2003. Information on potential predictors was collected at the scene. Outcomes were measured during a 3-month follow-up. Data were analyzed with modern data-mining procedures in which true forecasts were evaluated. A screening instrument was developed based on a small fraction of the information collected. Making the screening instrument more complicated did not improve forecasting skill. Taking the relative costs of false positives and false negatives into account, the instrument correctly forecasted future calls for service about 60% of the time. Future calls involving domestic violence misdemeanors and felonies were correctly forecast about 50% of the time. The 50% figure is important because such calls require a law enforcement response and yet are a relatively small fraction of all domestic violence calls for service.

“Do You Know What It Feels Like to Drown?” Strangulation as Coercive Control in Intimate Relationships

Strangulation is a unique and particularly gendered form of nonfatal intimate partner violence, affecting 10 times as many women as men. Medical research documents multiple negative health outcomes of such victimization, and in the past decade nearly 30 U.S. states have enacted laws making nonfatal strangulation a felony. We extended prior work by using grounded theory in a qualitative study to explore women’s experiences of, thoughts about, and reactions to being strangled. Each of the 17 mostly well-educated and African American domestic violence shelter residents had been strangled at least once by an intimate partner; most had survived multiple strangulations. Despite other severe abuse and a high level of fear, all were shocked that their partner strangled them. Participants reported an intense sense of vulnerability when they recognized during the assault how easily they could be killed by their partner. Nonetheless, they seemed to think of strangulation, not as a failed murder attempt, but as a way to exert power. Efforts to extricate themselves from a “choking” largely failed and resistance resulted in an escalation of the violence. Moreover, strangulation is difficult to detect which, as participants observed, makes it especially useful to the abuser. The aftereffects permeated the relationship such that strangulation need not be repeated in order for her to be compliant and submissive, thus creating a context of coercive control.

Handgun sales, beer sales, and youth homicide, California, 1972-1993.

Whether regulating access to firearms and alcohol will reduce violent injuries is an important policy question. Empirical answers are difficult to obtain because only observational data are available. The present study estimated the association of firearm sales and alcohol sales with subsequent homicides, after adjusting statistically for potential confounders (e.g., unemployment rates) using California data from 1972 through 1993. Handgun sales and beer sales were lagged one year and used to explain variation in the homicides of Californians (e.g., 1990 sales were used to explain 1991 homicides). Differences across population groups were investigated, with a focus on 15- to 34-year-olds, the highest risk age group. Even when taking potential confounders in the base population into account, beer sales and handgun sales generally are associated positively one year later with homicide, particularly among young men. Reducing beer sales may reduce homicides. And, although they represent a small fraction of existing firearms, regulating the number of handguns sold may reduce the number of homicides.

Knowing a Sexual Assault Victim or Perpetrator A Stratified Random Sample of Undergraduates at One University

Rape awareness and prevention programs are common on college campuses and a potentially useful way to reach large numbers of young adults. One largely unexamined potential mediator or moderator of program effectiveness is the personal knowledge of student audiences. In this study, we assess the prevalence of knowing a victim and, notably, a perpetrator of sexual assault. A stratified random sample of 2,400 undergraduates was recruited for an online survey about sexual assault. A total of 53.5% participated and yielded a sample representative of the student body. Sixteen questions were modified from the Sexual Experiences Survey to assess whether participants knew a victim of any one of eight types of sexual assault. Findings indicate that students begin college with considerable personal knowledge of sexual assault victimization and perpetration. Nearly two thirds (64.5%) reported that they know one or more women who were a victim of any one of eight types of sexual assault, and over half (52.4%) reported that they know one or more men who perpetrated any of the types of sexual assault. Most students reported knowing victims and perpetrators of multiple types of assault. Knowledge varied substantially by gender and ethnicity. Students’ preexisting personal knowledge should be included in assessments of program effectiveness and, ideally, in program design.

A Systematic Review of the Epidemiology of Nonfatal Strangulation, a Human Rights and Health Concern

We reviewed the literature on the epidemiology of nonfatal strangulation (also, albeit incorrectly, called choking) by an intimate partner. We searched 6 electronic databases to identify cross-sectional, primary research studies from 1960 to 2014 that reported national prevalence estimates of nonfatal strangulation by an intimate partner among community-residing adults. Of 7260 identified references, 23 articles based on 11 self-reported surveys in 9 countries met the inclusion criteria. The percentage of women who reported ever having been strangled by an intimate partner ranged from 3.0% to 9.7%; past-year prevalence ranged from 0.4% to 2.4%, with 1.0% being typical. Although many epidemiological surveys inquire about strangulation, evidence regarding its prevalence is scarce. Modifying or adding a question to ongoing national surveys, particularly the Demographic and Health Surveys, would remedy the lack of data for low- and middle-income countries. In addition, when questions about strangulation are asked, findings should be reported rather than only combined with other questions to form broader categories (e.g., severe violence). Such action is merited because of the multiple negative short- and long-term sequelae of strangulation.

Violence Against Women and Household Ownership of Radios, Computers, and Phones in 20 Countries

Objectives To examine the relationship between household ownership of information and communication technologies (ICTs) and justifications for wife beating. Methods Women aged 15 to 49 years in 20 countries were surveyed via UNICEFs Multiple Indicator Cluster Surveys between 2006 and 2014. Multivariate logistic regressions accounted for individual-, household-, and structural-level variables. Results Household ownership of any ICT (radio, computer, fixed phone, or mobile phone but not television) was associated with increased odds of women rejecting wife beating. The largest association was with computer ownership: women in homes with a computer were more likely to reject wife beating (adjusted odds ratio [AOR] = 1.81; 97.5% confidence interval [CI] = 1.69, 1.93). Number of ICTs was important: women in households with 1, 2, 3, 4, and 5 ICTs (vs 0) were more likely to reject wife-beating justifications (AOR = 1.10 [97.5% CI = 1.03, 1.17]; AOR = 1.10 [97.5% CI = 1.03, 1.18]; AOR = 1.19 [97.5% CI = 1.11, 1.29]; AOR = 1.71 [97.5% CI = 1.54, 1.88]; and AOR = 2.85 [97.5% CI = 2.48, 3.26]; respectively). Conclusions Independent of household wealth, country development, and other sociodemographic factors, the more ICTs in a household, the more likely that women will reject wife-beating justifications. Policymakers and program planners should consider potential implications of ICT access relating to intimate partner violence.

“Consent is Good, Joyous, Sexy”: A banner campaign to market consent to college students

ABSTRACT Objective: This study assessed the recall of, reaction to, and understanding of a brief campus banner campaign promoting consent in sexual relationships, and determined whether campaign exposure was associated with subsequent engagement in activities related to sexual assault education, awareness, and prevention. Participants: A stratified random sample of 1,200 undergraduates was recruited during fall of 2010; 628 (52.3%) participated. Methods: To account for history and maturation, an experimental research design was employed with an online survey. Results: Direct and indirect campaign exposure was associated with increased action. Students expressed primarily positive reactions to and appeared to understand the consent message. The campaign appealed to and was associated with increased activity among a wide range of students with one exception: a negative effect was observed for business students. Conclusions: Colorful banners with pithy, upbeat messages hold promise for engaging undergraduates in conversations and proactive activities related to sexual assault prevention.
